    ow pulse from sensor and calculating data. The measuring CPU exchanges and controls da fuel dispenser ta or information through the process circuit of communication signal and cente fuel dispenser r-control computer. EEPROM: generally, fuel dispenser adopts model 24C16 of EEPROM, which is used for memorizing calculated information, unit price, oil density, etc. The IC chip matched with measuring CPU mainly has the memory chip of calculating data, like HX1215 and 24C16. 2.2 Keyboard At present, there are two types of keyboard used on fuel dispenser, parallel scan keyboard and serial scan keyboard. Different manufacturers employ various model keyboards with these logical units that illustrated in Diagram 3-2, 3-3 and 3-4 in their fuel dispensers. Diagram 3-2: Keyboard sketch map of fuel dispenser Diagram 3-3: Structural sketch map of parallel keyboard Diagram 3-4: Structure sketc fuel dispenser h map of serial keyboard Liquid crystal displays are adopted in keyboard screen and main display screen on which showing unit price, volume and sales. The components installed on keyboard varied largely, some manufacturers adopting touch switch, others membrane key or rubber keyboard. Parallel keyboard, high speed with many lines, is restricted by data signal length due to interference. However, serial keyboard with high anti-jamming and few lines is much freer from the length of data line. Both serial keyboard and parallel keyboard are feasible plans. 2.3 Main display screen Liquid crystal display (LCD) is generally adopted as main display board of fuel dispenser recently because it is clean and beautiful in sunlight. In order to be visible at night, transparent or semi-transparent liquid crystal screen is adopted against matrix backlight board with light-emitting diode, which also have hearting function. Display usually adopts 6-6-4 type illustrated in Diagram 3-5, showing 6 digits on volume and money, 4 digits on unit price, each item data has two digits after decimal point.

    one mineral   insulated cable that is a candidate for forecourt installation mee fuel dispenser ts the American   standard UL1581. The cable manufacturer states that U fuel dispenser L1581 is equal to the IEC 332-   3 standard. This may be the case but the cable is labelled UL1581 along its length. It is   not clear whether national approval bodies in other countries will accept this since   their procedures for approval are in some cases by visual inspection. They will expect   to see a cable labelled IEC 332-3.  4.6 Re-use of Existing Cables   Not withstanding the previous paragraph on cable types existing twisted-pair cables   have been re-used in IFSFLon implementations in Ireland France Spain Portugal  Version 2.13 Page 5 of 24 December 2004   IFSF ENGINEERING B fuel dispenser ULLETIN NO. 1 CABLES CABLING and CABLE CONNECTORS   and Sweden. Cables in Italy and Greece that were untwisted needed to be replaced. It   is anticipated that in most other EU countries any existing twisted-pair cables installed   between the site controller and the dispensers will work satisfactorily with an FTT   network.   Although these twisted-pair cable types (given in Appendix B) are not yet qualified by   Echelon in all cases existing cables and cabling topologies have been re-used.   Samples of the existing cable should be tested in the laboratory to ensure that network   performance is satisfactory. Note that this means testing at least a 200 metre sample   since it is the length not the transfer rates which is compromised by failure to meet   the Echelon electrical specifications.  4.6.1 Active Hubs   Where existing cable is shown not to work it is possible to re-use the existing cabling   using an active hub. The active hub replaces the primary junction box and functions as

    . Mr Bush s problem is that, with the exception of Jimmy Carter and John McCain, no pro fuel dispenser minent politician seems inclined to speak out on his side. With mid-term electi fuel dispenser ons looming in November, Congress may well find enough votes to override the presidential veto. As with CNOOC, politicians are claiming that this is less about protectionism than about the purchase of American assets by firms that are, in effect, arms of a foreign government. Continental Stevedoring & Terminals, one of P&O s partners, has filed a lawsuit in Miami claiming that under the sale it will become an “involuntary partner� with Dubai s government. The dockworkers union says it is ownership by a foreign government that scares its members most. Yet Dubai is much more obviously a friend of America than is China. And, anyway, is this really what this dispute is about? The most persis fuel dispenser tent complaint, heard also from families of victims of the September 11th attacks (some of the terrorists had links to the United Arab Emirates), is that it will imperil America s national security. Critics protest that the deal has not been adequately vetted. The Committee on Foreign Investment in the United States (CFIUS), which includes representatives from the Departments of Defence, State, Treasury, Commerce and, most important, Homeland Security, approved the takeover in the minimum 30-day period. Critics say it must have been superficial, and they are furious that the deliberations behind the decision are classified. Inevitably, too, there is a business connection to the Bush administration. The sort of people who claim that the White House is a subsidiary of Enron and or Halliburton have spotted a link between DP World and John Snow, the treasury secretary, whose agency heads the federal panel that signed off on the sales. Mr Snow used to run CSX, a railroad company that, after he had left, sold its port operations to the Dubai firm for $1.15 billion in 2004. Underneath all the posturing is one legitimate worry ports are one of
